Advanced Placement (AP) Biology (also known as AP Bio) is an Advanced Placement biology course and exam offered by the College Board in the United States. For the 2012–2013 school year, the College Board unveiled a new curriculum with a greater focus on "scientific practices".
Advanced Placement (AP) Human Geography (also known as AP Human Geo, AP Geography, APHG, AP HuGe, APHug, AP Human, HuGS, AP HuGo, or HGAP) is an Advanced Placement social studies course in human geography for high school, usually freshmen students in the US, culminating in an exam administered by the College Board.
Meanwhile, AP Physics 2 covered the other content areas. In 2020, the sound, waves, and electricity topics were removed from AP Physics 1 and moved to AP Physics 2. In 2024, the unit covering fluids was moved from AP Physics 2 to AP Physics 1, making space in the AP Physics 2 curriculum for more detail on waves and modern physics. [2] [7]
[3] The spider monkey has an arboreal habit and rarely ventures onto the forest floor. The brittle star has the habit of breaking off arms as a means of defense. Mode of life (or lifestyle, modus vivendi) is a concept related to habit, and it is sometimes referred to as the habit of an animal.
The 1972 Biological Weapons Convention is an international treaty banning the development, use or stockpiling of biological weapons; as of March 2021, there were 183 states parties to the treaty. [3] Bio-agents are, however, widely studied for both defensive and medical research purposes under various biosafety levels and within biocontainment ...
Taxonomy and replication strategies of different types of RNA viruses. An RNA virus is a virus characterized by a ribonucleic acid based genome. [1] The genome can be single-stranded RNA or double-stranded (). [2]
There are many reasons why underwater archaeology can make a significant contribution to our knowledge of the past. In the shipwreck field alone, individual shipwrecks can be of significant historical importance either because of the magnitude of loss of life (such as the Titanic) or circumstances of loss (Housatonic was the first vessel in history sunk by an enemy submarine).
Vegetation can also reduce the surface compaction of the soil which again allows for increased infiltration. When no vegetation is present infiltration rates can be very low, which can lead to excessive runoff and increased erosion levels. [3] Similarly to vegetation, animals that burrow in the soil also create cracks in the soil structure.
